A look at transcripts of Clinton stump speeches since she kicked off the general election campaign on Labor Day finds the Democratic candidate almost never talks about Obamacare. She doesn’t promise to expand it. She doesn’t promise to protect it. She doesn’t extol its benefits. She just doesn’t mention it.

There’s no doubt Obamacare is in trouble. Enrollment in the exchanges has fallen far short of projections. The purchasers of policies have turned out to be older, and in need of more care, than expected. Major insurers are pulling out of the exchanges altogether. Premiums are going up. Deductibles are skyrocketing, meaning many are left to pay most of their healthcare costs themselves.
